BREAD RAISING AND WARMING CABINET.

To all whom it may mean;

Be it known that I, -WILlE .AsKEW, a

citizen of theUnited States, residing at Morgan City, inthe parish of St. Mary and State of Louisiana, have invented certain new and useful Improvements in Bread,

Raising and Warming Cabinets; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enableothers skilled in:

the art to which it appertains to make and use the same. I e I r This invention relates to apparatus used for warming food, and more particularly to an apparatus of the character referred to especially designed for raising and warming bread and keeping vegetables and various articles of food which have been prepared for the table in a warm'condition ready to be served.

The invention will first .be hereinafter more particularly describedpwith reference to the accompanyingdrawings, which are to be taken as a part of this specification,

and then pointed-out in the claims atthe end of the description.

Figure 1 of said drawings represents a front elevation of my bread raising and warming cabinet; V g i Fig. 2 is a vertical sectional elevation of thesaineyf Fig. 3 is a vertical sectional elevation of the same at right angles'tothe section shown in Fig. 2, the section being taken on the line 33 of Fig.1; and a Fig. 4 is a sectionaltop plan view of the oven or food receptacle which is remo'vably fitted within the outer casing or cabinet.

Referring to said drawings, in which the same reference charactersor letters are'used to denote corresponding "parts in different views, the letter A may denote an outer cas-' ing or cabinet proper, preferably made-of wood and box-like in form, and having its interior lined with 'zinc, sheet metal ,or other suitable material; The cabinet is'mounted on legs B, B, adapted to support it'at' a suitable height abovefthe floor of the: room in which it is used, and it is providedjwith; an open front which is closed by a tightly fit ting hinged door at, having asliding bolt a thereon arranged to, engage an eye or staple a onthe cabmet for holding the door in a closed position. Within the cabinet or outer casing A isplaced' an oven or food receptacle C whichis prefer'ably'constructed of Specification of Letters Patent.

' sheet metal and in box-like form, and removably supported within the cabinet and spaced therefrom at top, bottom and on all four sides, to permit a free circulation of Warm or heated air around the oven orbetweenthe same andthemetallic lining of the outer casing. The oven 0 has a hinged door 0 which ispreferably formed of sheet metal and with a marginal flange 0 adapted to overlap the edges of the oven on all four sides so as to grip'the same and hold the lid in closed position by frictional contact be tween theedges of the oven and saidmarinal flanges. A series of shelves 0 are provided within theoven on whichpans con taining dough or other articles of food may be placed; said shelves beingsuitably spaced and supported on brackets 0 which may be bolted or. otherwise secured on the inner side of theoven so as to adapt the shelves to be removed for cleansin purposes. Tothe underside or bottom of t e oven may be secured, by bolts orrivets, metal brackets 0* adapted to holdvthe oven a suitable distance above the bottom of the casing A, and betweensaid brackets'is secured a deflector D which may. consist ofa sheet metal plate having oppositely inclined wings, the edges of which are secured by bolts or rivetsto the bottom ofthe oven sothat oppositely inclined surfaces are presented so'that the warm or heated air enteringthrough an openinga in the bottom of the'casing will be divided and distributed in equal .portions on opposite sides of the oven, and may pass'to and through" the spaces betweenthe outer sides of the oven and theinner sides of'the casing A to and along the space between the oven top" and the .inner wall of the casing and escape throug'hjan opening a? in the'top of-the casing.

f To the underside or bottom of the casing A is attached a heating chamber E within which may be placedany suitable heat producing device, such as a lamp or electric heater, by which air entering the chamber E through perforations '6 may be-heated and allowed to pass upwardly through the opening a in the bottom of the casing A, and from thence through the space between the interior of the casing and the oven, for warming the contents of the oven. The lamp chamber E has an open side which is closed by a door e, which is provided with an ordinary sliding bolt or latch e for holding it in closed position. The lamp chamber E is preferably constructed of sheet metal with an open top in which is fitted a metallic plate 6 which is bolted to the bottom of the casing A and serves to protect the wooden bottom from the heat within the heating chamber or lamp case. 'llhe plate has a marginal flange through whlch bolts or rivets are inserted for securing it to a lamp chamber, and also a central opening with a marginal flange which enters the opening a in the bottom of the cabinet and protects the wood from the heater.

For automatically controlling the escape of heated air and likewise the flow of cool air into the cabinet through the perforations 6 so as to maintain a uniform temperature within the cabinet, a thermostat G, of the form shown, or any desired form, such as is commonly used for heat regulating purposes, may be mounted on the cabinet and adapted by expansion and contraction, under varying degrees of temperature, to open and close a valve 9 on the end of a lever 9 pivotally mounted on top of the cabinet; said lever having adjustably secured on the threaded shorter arm thereof a counterweight g and having a rod 9 pivoted thereto at one end and depending through an opening in the top of the casing and connected with a device 9 within the casing, which is adapted by expansion and contraction to raise and lower said lever when the temperature within the cabinet is raised or lowered. I also preferably attach to the door of the cabinet, on the inner side thereof,

a thermometer H which is exposed to view.

through an openinga so that the temperature within the cabinet may be readily ascertained at any time, and the thermostatic device may be adjusted sO as to maintain within the cabinet a uniform temperature at all times.

When the temperature within the cabinet rises, the valve 9 permits the hot air to es cape and the resultant circulation within the cabinet allows a flow of cooling air to enter through the perforations e in the lamp box, whereupon the temperature becoming lower the valve 9 closes and shuts off the inflow of cool air and the cabinet heats up again. It will be seen that this cycle of operation is entirely automatic and the cabinet is kept at an even temperature at all times. It will likewise be noted that the heat from the lamp remains constant, but the entrance of cooling air is regulated by the efllux of heated air at the top caused by the opening of the valve.

I thus provide an apparatus of the character referred to which consists of few parts arranged in convenient form for use in keeping bread, meat and other articles of food warm for any desired length of time, so that such articles having been previously prepared for the table may be placed within the oven and kept warm until ready to be served. The apparatus is especially designed and adapted for use in raising bread, by placing pans of dough on the shelves within the oven and lighting the lamp or other heat producing device so as to introduce heated air into the cabinet in such manner that it will circulate around the oven and escape through the opening a at the top, when the tempera ture has risen enough to cause the thermostat A to open the valve 9, and when the temperature is lowered said valve will be automatically closed, and thus a uniform temperature within the cabinet will be maintained. In coldclimates, where houses are not kept Warm all night, this cabinet can be used to keep fruits, vegetables, eggs and other articles warm throughout the night. The oven is adapted to be readily removed to permit the interior of the cabinet to be cleaned, and 1 the shelves within the oven are also removable for cleansing purposes.

Preferably the door of the cabinet and also the door of the lamp chamber, if desired, may be provided with a blind bolt or device adapted to be opened only by one knowing the combination, so as to prevent children and inquisitive or unauthorized persons from having access to the cabinet or lamp chamber. The door of the lamp means for heating and introducing heated air in said casing through said bottom open ing, means for automatically controlling the escape of air from the casin through said top opening, and a closed food receptacle within the casing spaced therefrom on all sides and at top and bottom to permit air entering through the bottom of the casing to circulate around said receptacle and escape through the opening at the top of the casing.

2. A bread raising and Warming cabinet comprising a metallic-lined wooden casing having an air inlet opening in its bottom and an air exit opening at its top, a closed sheet-metal oven within said casing spaced therefrom on all sides and at top and bottom to permit the air to circulate around it and having a series of shelves supported therein, a heat producing device at the bottom of the casing in communication with said inlet, and a thermostat for actuating a valve controlling the escape of air through said exit, whereby a uniform temperature may be maintained within the casing. a

3. A bread raising and warming cabinet,

lit

comprising a casing and an interior receptacle spaced therefrom; said casing having an exit at its upper part communicating with the space between the casing and receptacle and provided with an inlet at the lower part of the casing and communicating with said space, means for heating said space between the casing and receptacle, and automatic means for introducing cooling air into said space. a

4. A bread raising and Warming cabinet comprising a casing, a spaced interior receptacle, means for constantly heating said space and thermostatically controlled means for admitting air to or excluding air from said space.

5. A bread raising and warming cabinet Gopies of this patent may be obtained for comprising a casing, an interior receptacle spaced therefrom, an exit at the top of the casing and communicating with said space, a heating chamber including a source of heat, communicating With said space, at the base of the casing; said heating chamber being provided with an air inlet, a thermostatically controlled valve for said exit, whereby a uniform temperature is maintained within said space. a

In testimony whereof I affix my signature in the presence of two Witnesses.
